NORMAN o. FLEMING, or Los ANGELES, CALIFORNIA,

BUCKET E013 DEEE-WELL PUMPS,

To all whomz't may concern: Y

Be it known that-I, NORMAN O. FLEMING, a citizen of the yUnited States, residing at Huntington Park, Los Angeles in the county of Los Angeles and State of California, have invented a new 1and usefullml proved Bucket for Deep-Well Pumps, of

which the following 4is a specification.

-My invention relates'to the pumping art,

and the principal object ofthe invention is;

to provide an improved bucket for use in a :deep well pump;

A further ob] ect of the invention is to'provide in such a bucket a valve which is` rigidlyxed to the pumpfrods, and which is so arranged that it moves positively with relation to the bucket.' f

A further object of the invention is yto y provide in such pump a bucket structure so arranged that the bucket turns in the pump cylinder, thereby distributing the wear over the walls of the cylinder and providing for a uniform wea-r of the valve seat.

A further object of the invention is to provide air chambers directly at the bucket for the purpose of cushioning the blow of the valve and preventing water hammer.

A further object of the invention is to provide an air chamber which is secured to the pump rod but which has openings immediately adjacent to the bucket for the purpose of cushioning the blow thereon.

The further objects and advantages will be made evident hereinafter or will be evident to one skilled in the pumping art from a perusal of the following specifications and inspection of the drawings.

` In the drawings, which are for illustrative purposes only,

Figure 1 is a section of the center of a portion of a pump embodying my invention.

Fig. 2 is a view on a plane, represented by the line 2 2 to Fig. 1, this plane being viewed in the direction of the arrows.

Fig. 3 is a view on a plane represented by the line 3 3 of Fig. 1, this plane. being viewed in the direction of the arrows.

My invention is adapted to be applied to single or multiple bucket pumps, but has a special utility in connection with the latter. It is illustrated as applied tol the upper bucket of a duplex pump, the piston rod of the lower bucket being shown at 11 and the piston rod :for the upper bucket being o the submergence.

conical seat 14 on which a bucket casting 15 'i seats. The bucket casting 15 slips inside a and through which the water 4.is lifted.; Cup

feo rpump cylinder 16 which is fixed in the wellv leathers 17, secured in place bythreaded rings 18,V serve to makea watertightjoint f between the bucket casting 15 and the pump cylinder 16. A series-of water openings 19:

are provided throughV thepiston 1.5,; these openings being separated by ribs 20 which are curved as shown in Figs. 2 and 3 so'thatq' the water: rushing upwardlyv therethrough tends to turn the bucket bodilyin the well.

.Thebucket vcasting 15 is also provided withacentral hub 21 which is bored out to slide freely through a limited distance on the pump rod 12, the lower limit of its movement being set by the contact oi the seat 14 and the upper limit being set by the lower end of an air chamber 22. This air chamber 22 is rigidly secured to the pump rod 12 and may be extended up through the well for a considerable distance. It is entirely closed except for an opening 23 at its extreme lower end, although a flexible hose 30 may beconnected into its upper end, the hose 30 being in turn connected at its upper end into a reservoir containing compressed air. A similar air chamber 24 is provided in the bucket 15, an opening 25 being provided in its lower end immediately adjacent Vto the valve 13. The method of operation is as follows: Cylinders 22 and 24 being lled with air, the parts Vare lowered into the well and this air is compressed to a degree equivalent to As the pump rod 12 is reciprocated, the valve 13 is moved. The pump leather 17 provides sufficient friction so that on the down stroke the valve 13 unseats from the bucket 15 allowing the water to pass between the bucket and the valve and upwardly Vthrough the openings 19. This upward movement of the water, dueV to the inclined ribs 20, twists the bucket at When the bucketreaches its extreme lower position and the movement of the rod 12 is reversed, the bucket re- Y mains momentarily stationary, the valve 13 compression of thel airinY the cylinders 22j and 24. The opening 25 is so placed that it tends to collect additional air irony-the- Water which runs through between the bucket 15 and the valve 13 oneach down- Ward stroke.

lf desired, the airvchamberQQ may eX- tend to a point close to the surface and compressedair may be delivered thereto through the flexible pipeSO, this air being maintained at aV pressure slightly below thatnecessary to torce air out through the openings 23. It is possible. to dispense With eitherthecylinder 22er 24, their action beingY cumulative.
